“…Thus, the appropriate value of bandwidth that needs to reserve at each link can be determined according to the user service level agreement (SLA). In the works of Hernández and Vila and Anjali et al, authors examined how to dynamically determine and adjust the optimal bandwidth reserved for traffic to minimize the resource consumption while still ensuring the service quality. Moreover, in related works,() authors researched how to use the multiflow aggregation bandwidth overprovisioning method to reduce the signaling overhead in bandwidth reservation.…”

Resource reservation protocol‐traffic engineering (RSVP‐TE) is one of the most widely used technologies to construct multiprotocol label switching tunnels across wide area network. In RSVP‐TE, along the path selected by the constrained shortest path first algorithm, resource is allocated using RSVP at each hop to provide deterministic end‐to‐end service quality, such as rate, delay, packet loss, and jitter. However, we argue that the flat and uniform bandwidth reservation mechanism of RSVP, which reserves the same bandwidth at each hop along the tunnel, ignore the difference of available bandwidth of these links, resulting in that the bandwidth of some congested links are quickly exhausted, whereas other links are not fully utilized. To further improve the load balancing and resource utilization of the network, a nonuniform bandwidth reservation (NUBR) method is proposed in this paper. With the proposed method, each node along the tunnel can flexibly reserve different bandwidth according to its own available resources. Thus, the reserved bandwidth at the congested links can be decreased by aggressively overreserving at idle links. In this paper, we introduce the concept of NUBR and explore the implementation based on the meter table of OpenFlow. The mathematical models and algorithms of NUBR have been studied under 2 application scenarios. At last, the simulation results show that the proposed method can allow more multiprotocol label switching tunnels than the traditional uniform bandwidth reservation method.

“…The initial solution is ⃗ C = {C i }. However, the initial solution may not be a feasible solution as it may not be able to meet constraint (7). In each iteration of Algorithm 1, while C ij of each link grows, the algorithm can always ensure that the links with more available bandwidth always reserve more.…”

“…Assume that the aggregate traffic flow has n frames and that the number of encoded bits produced by frame i is E i . If the flow source is constrained by a token bucket, then it cannot transmit more than b+rt bits at time t. Considering f frames per second, and ignoring the finite capacity of the bucket, the bucket fullness (in bits) at the end of the frame period i is [10,11]:…”

1This paper presents methods and tools for the optimal dimensioning of Differentiated Services Networks and, in particular, for the Expedited Forwarding Class of Service. The proposed method minimises the bandwidth reservation of a traffic aggregate to provide a given maximum delay. The paper also introduces several methods to generate multimedia traffic aggregation using real video traces. The method is evaluated in several scenarios using these traffic traces. The results of these simulations allow us to discover the relationship between a required delay and the necessary bandwidth reservation (or the achievable utilisation limit). An interesting conclusion of these scenarios is that, following several recommendations, the link utilisation can reach values of around 80% or higher. The advantages of using shortterm provisioning versus long-term provisioning are also studied.

“…The reservation is based on the worst bitrate value, generally a non representative peak. Token bucket parameters may be set to an average value to optimize the link usage but it may increase the network delay [6]. A trade-off is proposed in [7], with an adapted joint rate and admission control.…”

International audienceIn home network, to manage network bandwidthusage, one solution is to control the server outgoing traffic witha token bucket policy. Hull-based token bucket parameter settingallows the guarantee of Quality of Service for variable bitratevideo streaming. Hull is an abstraction of the bitrate, followingthe bandwidth requirement evolution dynamically. In the case ofmulti-streaming, we investigate a shifting technique to reducethe peaks impact. Postponing the streaming starting time ofa video helps to decrease the maximum required bandwidth.The technique is then mixed with the hull-based reservation.Simulations show the effectiveness of the combined approachesto optimize bandwidth usage, guaranteeing the best QoS forstreaming. Online utilization is also discussed
